wehewehe:

Loaʻa i ka Silicon Carbide ka waiwai o ka maikaʻi kūʻokoʻa-corrosion, kiʻekiʻe mechanical ikaika, kiʻekiʻe thermal conductivity, maikaʻi pono lubrication i hoʻohana ʻia e like me nā maka sila, nā bearings a me nā paipu i ka spacecraft, machinery, metallurgy, paʻi a me ke kala, meaʻai, lāʻau lapaʻau, ʻoihana kaʻa a pēlā aku. ma. Ke hui pū ʻia nā maka sic me nā maka graphite ʻo ka friction ka mea liʻiliʻi loa a hiki ke hana ʻia i mau sila mechanical i hiki ke hana i nā koi hana kiʻekiʻe.

ʻO nā ʻano kumu kumu Silicon Carbide:

-Haʻahaʻa haʻahaʻa

-Kiʻekiʻe thermal conductivity (kokoke i ka alumini)

-Ke kū'ē i ka haʻalulu wela maikaʻi

-Ka wai a me ke kinoea hōʻoia

-Ka refractoriness kiʻekiʻe (hiki ke hoʻohana ʻia ma 1450 ℃ i ka ea a me 1800 ℃ i ka lewa kūlohelohe)

-ʻAʻole ia e hoʻopilikia ʻia e ka corrosion a ʻaʻole pulu me ka alumini hoʻoheheʻe a i ʻole ka zinc hehee

-Ka paakiki kiʻekiʻe

-Haʻahaʻa friction coefficient

-Abrasion kū'ē

-Ke kū'ē nei i nā ʻakika kumu a ikaika

-Polisheable

-Ka ikaika mechanical kiʻekiʻe

Hoʻohana Silicon Carbide:

-ʻO nā sila mīkini, nā bearings, nā pahu pahu, etc

-Nā hui wili

- Semiconductor a me ka uhi

-Pads Pump mau mea

- Nā mea kemika

-Nā aniani no nā ʻōnaehana laser ʻoihana.

- Nā reactors kahe mau, nā mea hoʻololi wela, etc.

Hiʻona

Hoʻokumu ʻia ka Silicon carbide ma nā ʻano ʻelua:

1) Pressureless sintered silika carbide

Ma hope o ka hoʻopaʻa ʻia ʻana o nā mea carbide silicon pressureless, ua hōʻike ʻia ke kiʻi kiʻi aniani ma lalo o ka 200X optical microscope i ka hāʻawi like ʻana a me ka nui o nā kristal, a ʻaʻole ʻoi aku ka nui o ka kristal nui ma mua o 10μm.

2) ʻO ka carbide silikona i hoʻopaʻa ʻia

Ma hope o ka hoʻopili ʻana i ka silicon carbide, hoʻomaʻamaʻa kemika i ka ʻāpana paʻa a maʻalahi o ka mea, ka aniani
ʻO ka hāʻawi ʻana a me ka nui ma lalo o ka microscope optical 200X he ʻano like, a ʻaʻole ʻoi aku ka nui o ka ʻike silika manuahi ma mua o 12%.
